Subject: Estimate row sizes for tables and indices and use those estimates during
X-Git-Tag: version-3.8.1~39
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3d8b2395b3fa3dc33be2a47a230e906894d55113;p=thirdparty%2Fsqlite.git

Estimate row sizes for tables and indices and use those estimates during
query planning.  Enhance the index_info pragma to show the estimated row
sizes and to show the estimated row size for the main table as well.  Allow
an alternative row size estimate to be specified in the sqlite_stat1 table.
